I have a Vortex Smart but have recently moved house and my new garage has no power. I therefore need a turbo that runs without power. Please could someone tell me if a Bushido Smart brake unit will fit on to a Vortex Smart frame? Looking at the photos, the only difference looks to be the colour?

As far as I can tell, these frames are the same, other than the paint job. I think they are all based on the original Tacx Satori trainer. I have inter-changed Genius, Bushido and Vortex brakes on this frame.

P.S. Why not run a long extension cord out to the garage. It's a lot cheaper than a new brake. These trainers consume a very small amount of power, so you don't need a heavy cord. The Bushido is more finicky to use than the other trainers in my experience. Doing firmware updates can be difficult at times.

You are right. The Satori frame is generally the same as for the Genius, Bushido, and Vortex, except the brake attachment portion on the rear of the frame is similar to the earlier Imagic/Fortius/Cycleforce frame (and similar magnetic trainers) that used the plastic extension pieces for different wheel sizes.

But I still believe that the Genius, Bushido and Vortex brakes use the same frame.
